Study start date: November 7, 2025

Actual date on which the first participant was enrolled.

This clinical trial focuses on encouraging preschool-aged children and their parents or caregivers to drink more water. The goal is to see if an intervention called Tap Trust can improve their experiences and trust in their home tap water, which in turn might boost their water intake. This is important because increasing water consumption can lead to healthier lifestyle choices and prevent the consumption of sugary beverages, which are linked to various health issues. During the study, families will participate in the Tap Trust program, which aims to enhance their confidence in the safety and quality of their tap water. The study will observe and measure changes in how much water the children and their caregivers drink. By assessing the effects of this intervention, researchers hope to find a simple way to encourage healthier drinking habits in families, with no significant risks expected from participating in the trial.
